Invalid Argument Exception

Getting this error trying to install, using PHP 7.3 on Raspberry Pi 4 (Buster),

pi@raspberrypi:~/cops $ php composer.phar global require "fxp/composer-asset-plugin:~1.1"
Changed current directory to /home/pi/.config/composer

[InvalidArgumentException]
Package fxp/composer-asset-plugin at version ~1.1 has requirements incompatible with your PHP version, PHP extensio
ns and Composer version:
- fxp/composer-asset-plugin v1.4.6 requires composer-plugin-api ^1.0 which does not match your installed version
2.2.0.

To me this looks like issue #477

To fix this you can do either of 2 things:

1 - install COPS from https://github.com/seblucas/cops/releases/tag/1.1.3

2 - install COPS from source with a dirty fix (download the old composer phar)

Install from source
git clone https://github.com/seblucas/cops.git
cd cops
https://getcomposer.org/download/1.9.0/composer.phar
php composer.phar global require "fxp/composer-asset-plugin:~1.1"
php composer.phar install --no-dev --optimize-autoloader

I have not checked if this still works or not. Just use option 1!

Thanks for the advice. Decided to go with option 1 and it worked like a dream. I don't know why I didn't do that first of all, I just like to make things difficult for myself I suppose.
